I was curious about installing Skype under Debian 12 (Linux pi4 6.1.0-13-arm64 #1 SMP Debian 6.1.55-1 (2023-09-29) aarch64 GNU/Linux) so I started to follow the Debian 11 procedure at
httphttps://www.eroprofile.com/m/photos/alan01346s://wiki.debian.org/skype. I hit a flood of errors, then I noticed it was trying to install the AMD version, not the ARM version. On looking further I'm not sure there even is an ARM version. Is there?
